When push comes to shove: The oxidative photoinduced electron transfer (PET) in anthrylmethylthiomaleonitrile derivatives is regulated by the intramolecular charge transfer (ICT) of the “push–pull” dithiomaleonitrile receptor. Selective complexation with palladium chloride switches off the ICT, stops the PET, and results in fluorescence enhancement (see picture).
